STAMP-MILL.

Application filed May 16. 1905.

To all whom t may concern.'

Be it known that I, EDWARD H. Morini, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles, State ofCalifornia, have invented a new and useful Improvement in Stamp-Mills,of which the following is a specification.

An object of this invention is to provide convenient or satisfactorymeans for quickly taking up the lost motion and for lubrieating the stemwith a dry or plastic packing.

Another object of the invention is to provide a practicallyindestructible guide for the stems of stamp mills.

Another object of the invention is to produce a guide which will allowthe removal of the stem, for repairs or other purposes. in a mostconvenient and rapid manner and allow the resetting of the same in truealinement with the least labor and loss of time.

Another object is to make provision for conveniently re-using thelubricating takeup packing from time to time.

My invention comprises a separable stuifing boX, having parts easilyremovable, constructed to serve as a guide for the stampstem.

The accompanying drawings illustrate the invention.

Figure 1 is a fragmental view showing a stamp mill embodying thisinvention. Fig. 2 is a fragmental detail at right angles to Fig. 1showing one of the guides. Fig. 3 is a side elevation in partial sectionof one of the guides constructed in accordance with this invention. Fig.4 is a plan of said guide, the stamp being shown in section. Fig. 5 is afront elevation in partial section of the said guide. Fig. 6 is a viewshowing the guide constructed with a solid gland. In each of the viewsthe stamp stem is shown.

1 is the timber guide girt of the stamp mill to which girt the stemguide 2 is fastened by bolts 3 and nuts 4. The guide comprises a boXconstructed in two sections, 5 and 6. The section 5 is fastened to thetimber guide girt l by shoulders 7 on the bolts 3 and seated in sockets8 in section 5. In such case, the bolts 3 may be screwthreaded at bothends and fastened to the timber guide Ichgirt 1 by nuts 9.

10 is a stu ng box or gland. Said gland may be made in sections 11, 12,as shown in Fig. 4, or may be made in a solid Specification of LettersPatent.

ring as shown in Fig. G. The gland l() is drawn down on the dry plasticpacking by bolts 13 and nuts 14; the bolts 13 being screwed intosections 5 and 6 of the boX and the nuts 14 screwed down on the gland.Preferably the boX sections 5 and 6 are interlocked b v offsets asindicated at 15.

16 designates internal annular shoulders on sections 5 and at one end ofthe bore of the box to form the bottom of an annular receptacle 17between said shoulder and gland 1() to contain a dry and plastic packing18.

19 and 20 designate rings of Tucks packing or some other tleXiblematerial to tightly close the ends of the chamber or receptacle 17 toprevent the escape of the lubricating material 18. The packing rings orwashers 19 and Q0 are designed primarily to act as wipers for the stem,and to collect and keep confined the triturated plastic packinginterposed between the washers which in the movement of the stem has atendency to disintegrate packing 1S. Furthermore, the elasticityv ofthese washers allows of the more steady compression of the plasticpacking 1S. and is efficient in preventing the vibration and jarincident to the reciprocation of the stem within the sections, howeverother resilient means may be used. such as a spring and wiper plate ofsoft metal.

In practical use. the section 5 of the box will first be fastened inplace on the timber guide girt 1, and then the gland 10 will be placedon the stamp stem 24; then the stamp stem will be brought into place inthe bore of section 5, the gland being on the stem above said section.The section 6 will be brought into place and fastened'by nuts 4.Preferably cnt washers 21 will be interposed between the section 6 andthe said nuts. Then the Tucks packing 19 will be inserted around thestem '24 and placed in position on the shoulder 1G at the bottom ofchamber 17 then the dry or plastic lubricating packing 18 will be placedin the chamber 17, preferably in loose form until the chamber 17 isfilled nearly to the top so as to allow for compressing into form; thenthe top ring 20 of Tucks packing or like material, will be inserted atthe top of the chamber 17 and the gland 10 screwed down until furtheradjustment is unnecessary. Preferably yokes 22 arranged to prevent saidbolts 4 from working loose are provided, and are placed over the ends ofthe bolts 3 and secured in place by nuts 28. lVhen it is desired toremove the stem, the section 6 and gland 10 vvill be loosened andremoved from the section 5, whereupon the stem Will be removed and thelubricating packing picked out and preserved for subsequent use. By thusproviding two chambered sections, one of which is provided with thesocketed bolt holes 8 and fastened to a support by the shouldered bolts3 by which the other chambered section 6 is detachably held in place,the outer section G is readily detachable whenever the gland has beenlifted free from the bolts 1B. The sections l1 and l2 of the separablegland are preferably held together by bolts and nuts 25, 26, so that bysimply removing the nuts from the bolts of the box and the gland, thestamp stem may be freed, removed and replaced.

From the foregoing it is clear that I have provided a guide for a stampstem capable of holding plastic packing and means to rcsilientlycompress the plastic packing so as to produce steady compression of thepacking and minimize vibration and jar.

hat I claim is:-

l. A guide for a stamp mill stem comprising separable semicylindricalsections each having an interior annular shoulder forming a seat, saidseat being adapted to accommodate a packing, a yielding Wiper carried bysaid seat and surrounding said stem, a Packing within said sections andresting on said wiper, a gland extending into the sections andsurrounding` said stem, an elastic Washer interposed betvveen said glandand packing, means for securing said gland on to said sections wherebythe packing is compressed, Webs on said sections having openings, boltsextending through said openings and adapted to secure the sectionstogether, and a yoke arranged to prevent said bolts from Working loose.

2. A guide for a stamp-mill stem comprising separable sections eachhaving an interior annular shoulder, said separable sections adapted tobe fastened together, and to the supports for same, a plastic packing,yielding means resting on said shoulders and supporting said packing, acylindrical gland extending in the bore of said sections, and means forsecuring said gland to said sections.

3. A guide for a stem of stamp-mill comprising separable semicylindricalsections, said sections having means Within its bore for the support ofa plastic packing, a resilient seat for said packing resting on saidmeans Within its bore, a gland adapted to surround said stem and toenter the upper portion of the semicylindrical sections, means on saidgland for adjustably forcing the plastic packing to the stem, websprovided on said semicylindrical sections having openings, and boltsextending through said openings and so adapted to tighten said sectionsto each other.

ln testimony whereof, I have hereunto set my hand at Los Angeles,California this 10th day of May 1905.
